Application
1. It is often used as a reagent in organic synthesis. Ethyl orthosilicate can be used as a catalyst or reaction intermediate to participate in a variety of organic reactions, such as esterification, etherification, etc. Its high reactivity and good solubility can promote the progress of organic synthesis reactions.
2. It is often used as a precursor for surface coating materials. It can be used to prepare special siloxane polymers in solution, and then applied to the surface of the material by coating, spraying or dipping. The siloxane coating formed in this way can provide good wear resistance and corrosion resistance, and can also improve the waterproof performance and weather resistance of the coating material.
3. It can also be used to prepare silicate glass or ceramic materials. By adding an appropriate amount of ethyl orthosilicate to glass or ceramic raw materials, after drying and sintering processes, the hardness, heat resistance and corrosion resistance of the material can be improved.
4. Can be used as an inorganic binder for refractory fillers and pigments, like precision investment castings.
5. Can be used as a second backup casting coating. It cures faster than colloidal silica system.
6. Can be hydrolyzed to form silicon dioxide (silica).
7. Can be used as a starting material for sol-gel process.
8. Can be used as a crosslinking agent for silicone adhesive.
9. Can be used as a binder in zinc-rich (corrosion resistant) coating.
10. Can be used as a chemical intermediate.
11. Can be used as a silane drying agent in sealing compositions.
